DIVX to M4A: Extract Audio from DIVX(DivX Video) Video to M4A(MPEG-4 Audio) with River Past Audio Converter, DIVX2M4A converter, conversion
What is
DIVX?
DivX is a brand name of products created by DivX, Inc. (formerly DivXNetworks, Inc.),
including the DivX Codec
which has become popular due to its ability to compress lengthy video segments into small
sizes while maintaining relatively high visual quality. The DivX codec uses lossy MPEG-4 Part 2 compression, also known as MPEG-4
ASP, where quality is balanced against file size for utility. It is one of several codecs
commonly associated with "ripping", whereby audio and video multimedia are transferred to a hard disk and transcoded.
Many newer "DivX Certified" DVD players are able to play DivX encoded movies,
although the Qpel and global motion compensation features
are often omitted to reduce processing requirements. They are also excluded from
the base DivX encoding profiles for compatibility reasons.
To convert from DivX video, you will need to either get the DivX codec from
www.divx.com, or use a compatible decoder
like ffdShow, which is part of CCCP.
What is
M4A?
Because of its exceptional performance and quality, Advanced
Audio Coding (AAC) is at the core of the MPEG-4,
3GPP and 3GPP2
specifications and is the audio codec of choice for Internet, wireless and digital
broadcast arenas. AAC provides audio encoding that compresses much more efficiently
than older formats, such as MP3,
yet delivers quality rivaling that of uncompressed CD audio.
To encode MPEG-4 audio, you need to have River
Past MPEG-4 Booster Pack in addition to your audio software.
